☸️ Kubernetes NGINX Ingress Controller: 10+ Complementary Configurations for Web Applications
Everything in the YAML snippets below — except for ingress configuration — relates to configuring the NGINX ingress controller. This includes customizing the default configuration.

Breaking Terraform files into composable layers
In these examples, I assume that users have deployed an nginx-ingress-controller to their cluster through the eks layer. This controller is responsible for creating an nlb and exposing Elasticsearch and Kibana to the internet through their ingresses.
-
Implementing TLS in Kubernetes
Now, you need to install the Nginx Ingress Controller so that it can redirect incoming requests to your payment app to use HTTPS. Since you've exposed the app using nodePort, you need to install the Ingress using a custom value file that specifies the service type to NodePort.

Kubernetes cannot upload files larger than 1MB
Kubernetes We have a kubernetes cluster which has a dropwizard based web application running as a service. This application has a rest uri to upload files. It cannot upload files larger than 1MB. I get the following error: ERROR [2017-07-27 13:32:47,629] io.dropwizard.jersey.errors.LoggingExceptionMapper: Error handling a request: ea812501b414f0d9! com.fasterxml.jackson.core.JsonParseException: Unexpected character ('<' (code 60)): expected a valid value (number, String, array, object, 'true', 'false' or 'null')! at [Source: ! 413 Request Entity Too Large! ! 413 Request Entity Too Large! nginx/1.11.3! ! Hide resultsI have tried the suggestions given in https://github.com/nginxinc/kubernetes-ingress/issues/21. I have edited the Ingress to set the proxy-body-size annotation. Also, I have tried using the configMap without any success. we are using kubernetes version 1.5. Please let me know if you need additional information.

Assign an External IP to a Node
So far, i've been following the example here to set up an nginx Ingress Controller and some test services behind it. However, I am unable to follow Step 6 which displays the external IP for the node that the load balancer is running on as my node does not have an ExternalIP in the addresses section, only a LegacyHostIP and InternalIP.

How to use ACM public certificate for Nginx ingress controller?
Also, of personal note, I highly recommend you use the "ingress-nginx" controller which has a huge community and is of much higher quality and flexibility than the "nginx-ingress controller by nginx inc". I've had a lot of success with dozens of clients with this controller. It rocks!

Questions about Blue/Green & Canary Deployments (Vanilla K8)
For example, the ingress project from NGINX has its own CRDs that give better control over service versions and blue/green and canary cutovers https://github.com/nginxinc/kubernetes-ingress/tree/v3.0.0/examples/custom-resources/traffic-splitting

ArgoCD Deployment on RKE2 with Cilium Gateway API
It has already been a couple of years since the Kubernetes Ingress was defined as a “frozen” feature while further development will be added to the Gateway API.

A Comprehensive Guide to API Gateways, Kubernetes Gateways, and Service Meshes
Kubernetes provides two APIs to achieve this, the Ingress API and the Gateway API.

Using k8s-apiserver as AAA server for microservices?
With all that said, K8s is not really meant to function as an API gateway to arbitrary services. You should look into API gateways such as NGINX, Kong or others, service meshes as others have already pointed out, or have a look at the K8s Gateway API the SIG is currently working on. The last one is in the early stages of adoption, but it could provide you with a nice way to do an API Gateway right in K8s.

Service Mesh Considerations
Keep an eye on the Gateway API GAMMA Initiative as it is currently evolving with the goal of streamlining how services meshes can implement the Gateway API and reduce some overlap.

Apache Apisix: Open-Source API Gateway and API Management Platform
The selling point for me was ability to configure it using Kubernetes CRD's and future support of the Gateway API (under development - <https://gateway-api.sigs.k8s.io/>).
Developers can version their API now within helm charts or even yaml templates held along the code in their repositories.

Sharing load balancers between containers
While you're learning about ingresses, also look into the k8s Gateway API, which is the next generation. https://gateway-api.sigs.k8s.io/
-
Exposing k8s services
The GatewayAPI model is quite different from the LB/ingress model, in the cluster it consists of gateway and route objects. Once the gateway is created routes connecting gateways to services are added. If you need to change how requests are distributed, the routes are updated but the gateway remains so the address and other configuration remains consistent. Gateways can be shared by multiple routes. Take a look at https://gateway-api.sigs.k8s.io/ its a bit terse but you will get the picture.
